This invention relates to cash registers and like machines and moreparticularly to selecting mechanism controlling certain elements of themachine during departmental registering operations.

The principal object of the invention is to provide novel mechanism forsuperseding the normal automatic selection of certain departmentalmechanisms of the register on each machine operation, so that otherdepartmental mechanisms may be selected for operation.

Another object of the invention is to provide drawer selecting mechanismand alarm selecting mechanism controlled through a single difierentiallysettable member.

Another object of the invention is to provide novel departmentalmechanism whereby a department drawer and its associated alarm may beselected so as to be operated by the main operating mechanism.

Another object of the invention is to provide novel drawer unlatchingmeans to supersede the departmental unlatching means.

The mechanism is shown embodied in the general type of machine disclosedin United States Letters Patent, No. 2,031,860, issued to Bernis M.Shipley, and more particularly disclosed in the application of FrankWerner for United States Letters Patent, Serial No. 207,244, whichissued on April 14, 1942, as Patent No. 2,297,805, and the copendingapplication of this applicant for United States Letters Patent, SerialNo. 226,690, which issued on October 6, 194 .2, as Patent No. 2,297,961,to which patents reference is made.

General description In departmental cash register it is desirable thatthe owner have complete control of all the mechanism and that each clerkhave control only over the departmental mechanism assigned to him.

The departmental mechanism of such registers normally includes a drawer,an alarm, a totalizer, and an indicator, together with special countersand printing devices. Of these components of a departmental register.this invention is particularly concerned with the selection andoperation of the departmental drawers and alarms as controlled byspecial departmental locks and as superseded by special controlmechanism. Because the machine in which this invention is embodied hasbeen described in detail in the Patents Nos. 2,279,805 and 2,297,961, towhich patents reference has been made, only a general description willbe given of the main operative features of the machine which areessential to an understanding of this invention.

Framework The framework of the machine consists of a left vertical frameplate 6| (Figs. 1, 7, and 10) and a right vertical frame plate 62 (Fig.7)

joined and supported by cross members 63, 64 (Fig. and others not shown,and by various journaled shafts and rods comprising transmission andsupporting mechanism. A drawer frame consisting in part of members 66,6'! and 68 (Fig. 10) is joined to the base of the machine and houses twodrawers 69 and 10 (Fig. 7) slidably mounted in a manner well known inthe art, said drawers being arranged side by side and each normally heldin closed position by a latch against the tension of a spring tending toeject it to open position.

Main operating mechanism and differential The machine in which thisinvention is embodied is known as the key lever operated type of cashregister, having key levers H (Fig. 1) pivotally mounted on a key levershaft 12 journaled in and extending between the frame plates 6! and 62.Loosely mounted mounted, by arms, on rod 13' journaled in and extendingbetween the plates 6| and 62 is a weighted key coupler I l lying acrossall the keys to the rear of shaft 12, as shown in Figs. 1 and 10,keeping the keys in their home position as determined by frame member61. As the forward end of a key is depressed it is rocked about shaft 12thereby causing the key coupler to be rocked about rod I3. Attached tothe right end of the key coupler is a plate 15 (Fig. 8) having pivotedto it, by a stud 84, a double rack 16 cooperating with pinion 11 so asto drive it counterclockwise, as seen in Fig. 8, one complete rotationfor each oscillation of the key coupler as actuated by the key on itsupward movement and by gravity on its downward movement; Pinion 'llis'secured to the main drive shaft 18 as is ratchet 19, which ratchetcooperates with a spring tensioned pawl 80 to prevent retrogrademovement of shaft 18. The teeth 8| of the rack, drive the pinion TI onthe upward. movement of the key coupler and the teeth 8'! drive'it onthe downward movement of the key coupler, causing said pinion to rotateonce for each complete oscillation of the key coupler. Teeth 8| are heldin mesh by spring I20, anchored on the key coupler by pivotal stud 85and on the rack by stud 86, holding the nose 82 against the front edgeof guide 83 which, upon reaching the top thereof, passes over to theinnor groove of said guide by reason of the pivotal center 84 meanwhilehaving moved to the other side of the line of centers 85 and 86. Rackmember 16 is timed to shift so as to have teeth 81 engage pinion 11 asthe key coupler starts back to home position, to complete the rotationof shaft 18.

Those keys performing differential functions are provided with cam slots381 such as those illustrated in Fig. 1, which slots cooperate with anassociated bar 83 fastened to an arm 89 of a segment pivotally mountedon shaft 90. When there are several keys associated with the same barand its segment, the segment is moved a distance determined by the shapeof the cam slot of the operated key. When lateral transmission of themovement of any key actuated segment is desired the segment is furnishedwith a rear arcuate' arm 9| having teeth cooperating with a pinion 92fastened on an associated shaft 93 journaled in the frame members 64.Thus, for example, if the movement of the key actuated segment justmentioned is to be transmitted laterally, such as to the associatedtotalizer wheels, a second pinion on shaft 93 cooperates with thetoothed arcuate arm 94 of another segment mounted on shaft 30 which hasa forwardly ex tending toothed segment arm 96 which actuates theselected associated totalizer wheel 98 or 93 or the printing wheel mt.This transmission mechanism is well known and is fully described inPatents Nos. 2,279,805 and 2,297,961, to which reference has been made.

A spring held locking pawl 97 is provided for each segment group,normally locking it by engaging a toe on an arm W3 on one of thesegments of a group, preventing positive movement of the whole segmentgroup connected to the associated transmission shaft. When a key isdepressed the pawl 97 is disengaged from arm [63 freeing the segmentgroup. As each key operated segment is represented by a segmentcooperating with the printing wheels me, the alining shaft lill, mountedbetween the printer frames (not shown) acts as a stop to prevent all thesegment groups from passing through the zero position. Thus, the segmentgroups at all times are either locked in the zero position or moved in apositive direction under control of the cam slots in the keys. Asdepartment selecting key I05 (Fig. 10) is the only key cooperating withits associated segment 241, the segment is not furnished with a lockingpawl, like pawl 91 (Fig. 1), but'has an auxiliary cam plate I H actingtherewith, said plate to be later described, by means of a lip 12!preventing positive movement of se ment 24'! and shaft I92 except whenthe key I05 or cam plate I l l is operated.

When keys are depressed, the key coupler M is caused to rock on shaft 3the difference between the centers of motion of the keys and the keycoupler, causing the key coupler to enter the notch H14 in those keys,locking them on in a manner well known in the art. As the ratchet l9 andpawl (Fig. 8) form a full stroke device the key coupler cannot return tohome position until it has been fully oscillated. Any of the keys, suchas the B clerks key 565 shown in Fig. 10, may be provided with a cut outportion I06 to cooperate with a special formation ill! of the under sideof the key coupler whereby, upon operation of such key, the leading edgeof the key coupler jams against the shoulder 163 of the key. stoppingfurther movement of the key. The key coupler having rocked upwardlyslightly, and being held in partly raised position by the full strokeratchet iii, the shoulder H39 of such depressed key is engaged by theedge H0, keeping the key hooked thereon in partly operated position butunable to move further. Keys furnishedwith such a cut out portion, likethe 13" clerks key just described, are for the purpose of raising thekey coupler to a position where other keys may be hooked thereto so thatfull depression of another key not having the cut I96, as that shown inFig. 1, will carry all the keys hooked to the key coupler through a fulloscillation. The key coupler has a spring latch edge I02 (Fig. 1) toby-pass normal keys onto the partially raised key coupler but whichprevents them from being dislodged therefrom. This flexible key couplerarrangement is well known and described more fully in the cited patents.

Totalizer engagement In the particular embodiment of this invention.herein shown, there are two departmental registering mechanisms eachhaving a totalizer, one of which 98 hereafter being referred to as the Atotalizer mounted on shaft I45 (Fig. 1), and the other 99 mounted onshaft I46 hereinafter being referred. to as the B clerks totalizer.

The machine is constructed to normally engage the A totalizer as(Fig. 1) on each machine operation if no superseding control is. used.Therefore, when the A key is depressed it does not fuction to select theA totalizer as that totalizer is normally conditioned to engage onoperation of the machine as will be explained. If the B key is depressedthe B totalizer is engaged which necessitates control of the totalizerselecting mechanism by the B key. The means for en aging thesetotalizers selectively will be but briefly described, being fully setforth in the patent and applications cited above.

The B clerks key I (Fig. 2) has cooperating therewith the cam plate III,both key and cam plate being rockably mounted on the shaft 12. A stud H2extending from the B key engages a notch in the cam plate III andcarries it with the 13 key whenever the latter is operated, but leavingthe cam plate III free to be moved counter-clockwise without causing thefinger operated key I55 to move, as is desirable in operations where theB totalizer is conditioned to be selected automatically withoutdepressing the 13 key. The cam plate III is notched to receive the keycoupler as is the key I55 and is returned to home position after amachine operation by the weight of the key coupler. As the cam plate III is rocked counter-clockwise, as seen in Fig. 2, either by depressionof the key or by being otherwise rocked automatically, stud I I3extending from cam plate II I travels upwardly in cam slot II4 rockingthe totalizer selecting plate H5 slightly clockwise from the normalposition shown (Fig. 2), to select the B totalizer for engagement in theensuing machine operation. As has been explained, the main drive shaft18 makes one rotation for each machine operation and in so doing rotatesa totalizer engaging drive cam H5 mounted thereon so as to rock a plateII1 mounted on shaft 95 first counter-clockwise and then clockwise.Studs I I8 and H5, extending from plate I I1, engage bifurcations in camlevers I and MI respectively, whose forward ends are pivotally attachedto pawls I 42 and I43 which are in turn pivotally mounted on one of thetotalizer frame plates I44.

The totalizers are mounted on shafts I 45 and I46 (Figs. 1, 2, and 3)each carried in a rockable frame, I41 and I 38 (Fig. 3) mounted onshafts I 49 and I supported between frame plates, one of which, I 54, isshown. The forward edge of the totalizer selecting plate I'I5 (Fig. 2)is notched to cooperate with shafts I45 and I45, and with pawls I42 and[43 for controlling the totalizer engagement. In normal rest position,shown in Fig. 2, the plate IE5 has a notch opposite shaft I45 and a highplace opposite the lower end of pawl I 52, a high place opposite shaftI45 and a notch opposite the lower end of pawl I43. On counter-clockwisemotion of plate H1, cam lever I40 is rocked clockwise around stud I 5|causing stud I 52 to be driven downwardly by the cam slot. Stud I52(Fig. 3) is carried by totalizer engaging lever I53 pivotally mounted ona plate I54 rockably mounted on shaft 90. As stud I52 is drivendownwardly a cam slot in the forward end of lever I 53 rocks thetotalizer frame, by means of shaft I45, in engaging motion toward thedifferential segments represented in Fig. 1 by reference numeral 96. Ifthe pawl I43 is not blocked from counter-clockwise motion, asillustrated by the notch opposite the lower end of pawl I43 (Fig. 2),the motion of cam lever I4I would rock pawl I43 counter-clockwiseinstead of moving the associated totalizer to engaged position as shaftI46 is blocked by a high place on plate II5. On operation of the Bclerks key, the plate H5 is rocked clockwise slightly so as to block outthe engagement of the A or upper totalizer and causing engagement of theB or lower totalizer, by presenting a high place to shaft I45, a notchto the lower end of pawl I42, a notch to shaft I46 and a high place tothe lower end of pawl I43.

Plate I54 (Fig. 3) may be rocked counterclockwise along with plate II1(Fig. 2) to prevent the engaging of either totalizer by causing pin I55to be lowered into slot I56 and slot I59 (Fig. 2) thus operativelyconnecting the two plates together. This result, accomplished bymechanism not shown, is accomplished by rendering the downward motion ofstuds I52 ineffective by causing the pivot points I51 and I58 to movedownward. This result, desirable in transactions where money is paidout, is not a part of this invention, and the mechanism foraccomplishing this result will not be described; however, reference maybe had to Patent No. 2,297,961, before cited, for the details of thismechanism.

Drawer mechanism Slidably mounted side by side in the base of thecabinet, are two cash drawers 39 and 10 (Figs. '7 and 10) each latchedin closed position, against the ejecting force of a spring tensioned armI22, by latches HI and I12 (Figs. 7 and 10) engaging latch plates I13and I14 on the respective associated drawer. Latch I1I is secured toframe supported shaft I15 (Figs. 7 and 10), and latch I12 is secured toframe supported shaft I16 (Fig. 7). Rocking either shaft clockwise, asseen in Fig. 10, releases the associated drawer to the spring action ofits ejecting mechanism. Each latch is provided with a pawl I18 to holdthe latch in unlatching position until the drawer is closed. This pawlis provided to require the drawer to be closed before the machine canagain be operated when the control lever I10 is placed in the properposition as will be explained in connection with the controls andinterlocks. Referring to the right drawer, as shown in Fig. 10, as anexample, when the latch I1I is operated, by the rocking of shaft I15clockwise, the drawer is released and pawl I18 is allowed to rockcounter clockwise, in response to the tension of spring I19, until it ispositioned to be engaged by shoulder I of the latch by the contact ofroller I 8!, with the arcuate surface I82. Under these con ditions thelatch cannot resume its normal latched position until pawl I18 isknocked back by the latch plate on the closing of the drawer to theposition shown in Fig. 10. Thus, shaft I15 is held rocked clockwise fromnormal position until the drawer is closed. This holding of shaft I-15in rocked position will, if the control lever 51%? be properlypositioned, prevent the machine from being operated.

Loosely mounted on the left end of shaft I15 is an arm 83 (Figs. 4 and7) to which is pivotally attached a link I84 (see also Fig. 3.5) havinga hook I85 at its upper end to engage the main drive shaft 13 so as tobe vertically slidable thereon between collars secured on said shaft.Extending from the right side of the hook is a stud I86 (Figs. 10' and15) adapted to be engaged by the periphery of a cam I81 having a highpoint I98 adapted to strlke-andlift th'estud I86 near the end of eachmachine operation thus raising the link I94. Secured to the inner endsof shafts H and H6 (Figs. 7 and are arms I99 and I99 respectively, armI89 having pivoted thereto link 495 and arm I90 having pivoted theretolink I96, each link having a hooked top to slidably engage shaft I8 in amanner similar to link E84. Link I84, a driving member, is selectivelycoupled either to link I95 controlling the latch for the drawer IE1, orto link I96 controlling the latch for drawer 69, by means of a plate camI9I (Figs. 10 and selectively positioned by means of the departmentcontrol mechanism to be described. Cam I9! secured to frame supportedtransmission shaft I92 (Figs. 7, 10, and 15) cooperates with thebifurcated portion of a lever I93 pivotally mounted by a pin I94,secured thereto, on link I84. The lower end of lever I93 ends in a hookI 93 adapted to engage a stud I91 extending from link I95 when the leverI93 is rocked clockwise by cam I9I as seen in Fig. 10. On the left endof the pin I94 is secured a hook 299 adapted to engage a stud I99 onlink I95 when the lever I93 is rocked counter-clockwise by cam 595.Therefore, the position of the cam 59! as positioned by shaft I92determines which one of the two links I95 and I96 will be coupled to thelink I84 to be raised thereby, and consequently determines which drawershall be unlatched on the operation of the machine. Shaft I92 ispositioned by the department key I05 and cam plate III (Figs. 2 and 10)as will be described.

Figs. 5 and 6 show a modified form of the drawer unlatching meansadapted to registers Alarm mechanism Associated with each departmentalmechanism of the machine is an alarm bell, the A de-- partment bell 2I6(Figs. '7 and 8) being securely mounted on stud 2II secured to frameplate 62 by screw 229, the bell being separated from the frame by awasher 22I. On a sleeve 222 on stud 2!! is mounted a hub 2 I9 havingsecured to it a lever 223 and the B departmental bell 2| 8 eccentricallymounted. Arm 223 (Figs. 8 and 9) is bifurcated to engage a stud 224extending from the forwardly extending arm of a segment 225 rotatablymounted on shaft 90. The armate rear arm'of segment 225 has teeth 226(Fig. 8) cooperating with pinion 221 (Figs. 7 and 8) secured on shaft I92 which shaft as before stated also positions the drawer selecting camI9I. In rest position, as shown in full line in Fig. '7, the strike rimof the A bell 2I6 is slightly farther from the aXis of the bell hammer228 than is the strike rim of the B bell, but by making the rightportion of the bell hammer of larger diameter than the left portion,upon movement of the hammer toward the bells only the A belly is struck.However, when the eccentrically mounted B bell is rotated by movement ofsegment 225 to the position shown by the broken line, the strike rim ofthe B bell is enough Ill) nearer the axis of hammer 228 to allow theleft half of the hammer stud to strike the B bell without the right halfof said stud striking the A The bell hammer is actuated by the movementof the key coupler in the following manner. Pivotally mounted on theplate I5 (Figs. '7 and 8) fastened to the key coupler is a lever 229normally held in the position shown in Fig. 8 by spring 239. As the keycoupler is raised, pivotal stud 23| is carried counter-clockwise aroundrod I3 as a center. A positionable guide member 232 (Figs. 7 and 9) whenin the position shown in Fig. 9 is adapted to be contacted by an ear 233on lever 229 (Figs. '7 and 9), as the key coupler is rocked upward,causing lever 229 to be moved clockwisely (Fig. 9) with relation toplate '15 against the tension of spring 239. As the ear 233 reaches thetop of the guide 232 the lever 229, no longer being under restraintthereof, respends to the tension of spring 239 tending to move it to itsnormal position relative to plate I5 and, in so doing, the leveroverthrows its normal position by reason of its inertia, carrying thebell hammer 228 held thereby against the selected bell. After strikingthe bell the spring 239 returns the lever to home position thus allowingthe bell to vibrate undampened by contact with the hammer.

Guide member 232 may be moved rearwardly which removes it from the pathof ear 233 thereby allowing lever 229 to move with the plate I5undisturbed relatively thereto, which consequent- 1y fails to producethe necessary motion for the hammer to contact the selected bell.

Secured to rod I3 (Fig. 8) is a lever 23 i hav ing its other endpivotally connected to a link 235 the outer end of which bears the guidemember 232. An aperture in frame plate 62 provides entrance of guidemember 232 to the inside of the frame where it may co-operate with ear233. A bearing stud 236 on link 235 (Fig. '7) extending through a guideslot in frame plate '62 limits the extent of movement and supports thefree end of link 235. By turning rod I3 (Figs. '7 and 9), by means of ahand lever 23! secured thereto, the bell may be made operative orinoperative. To control this bell mufiler mechanism by the control shaft238 (Figs. 7 and 8) to be fully described, said shaft has secured to itsright end a cam 239 (Fig. 8) having cam follower 2 19 (Figs. 8 and 9)cooperating therewith. Cam follower 249 is secured to lever 2M pivotallymounted on frame plate 52 by stud 242 in such a manner that clockwisemovement of cam 239 rocks lever 24I counter-clockwise andcounter-clockwise movement of cam 239 rocks lever 2 H clockwise. Lever2II in its most counter-clockwise position is shown in Fig. 9, in whichposition the rear end of lever 24I blocks movement of link 2335 holdingit in forward position where guide 232 enables the hammer to strike theselected bell. If the link 235 is in its rearmost position the end oflever 24I will lock the hammer mechanism in disabled position.

Drawer and alarm selecting mechanism The machine of the presentembodiment having two departmental registering mechanisms denominatedfor this disclosure as the A clerk and B clerk departments, there areprovided an A clerks key 243 (Fig. '7) to be operated on transactionsconducted by the A clerk and a B clerks key I05, previously mentioned,to be operated on'transactions conducted by the B clerk.

The A totalizer being normally engaged as explained, the machine is alsoarranged to normally operate the A drawer latch and to ring the A alarmbell, even though the A clerks key is not used. As is shown in Fig. thehook I98 normally engages the stud I91 on link I96 so that nodifferential rotation of shaft I92 is needed, on operations of the Adepartment, to select the A drawer. The A alarm bell 2I9 (Fig. 7) is inposition to be struck if there is no movement of shaft I92. Therefore itis not necessary for the A key to be used for the selection of the Adepartment of the register.

If the B department is to be selected the B key must ordinarily be used,the exception to be later explained. The auxiliary plate II I (Fig. 2),rocked through stud I I2 on operation of the B key I85, has a cam slot245 which cooperates with a bar 249 projecting from a segment 241 (Figs.'1 and 18) which is rockably mounted on shaft 98 and which has a toothedrear projecting arm cooperating with pinion 248 pinned to shaft I92,said shaft being turned a certain fixed angle on depression of the B keyand then turned back to home position as the B key returns home.

When shaft I92 is turned by operation of the B key the cam I9I (Fig. 15)is turned with it which rocks lever I93 disengaging hook I98 from studI91 and engaging hook 294 with stud I99, thus connecting link I94 to thelink I95 so as to cause the B drawer to open when cam I81 lifts the linkI84 on operation of the machine.

Shaft I92 has fastened to its right end the pinion 221 (Figs. '1 and 8)which cooperates with segment 225 rockably mounted on shaft 98. Segment225 in being rocked moves the 3" bell to a position where it may bestruck as before explained.

Thus, operations of the machine involving the movement of cam plate IIIselect the B totalizer, the B drawer opening mechanism, and the B alarmmechanism.

Departmental locks Loosely mounted on shaft 215 is a lever 2-16 (Figs.10, 11, 12, and 13) having a notch 211 on a forwardly extending arm, andhaving a second arm 218 (Fig. 11) extending to the right which isriveted to a lever 219 (Figs. '1 and 10) also loosely mounted on shaft215. Lever 219 has a downwardly extending arm forming a hook 288 adaptedto engage a stud 28I (Fig. '7) on the B key when said lever 219 isrocked clockwise from the position shown in Fig. 10 to that shown inFig. 12, and to release said stud 28I when rocked counter-clockwise asshown in Figs. 10 and 13. The position of stud 28I is representeddiagrammatically in Figures 18, 11, and 12. When the hook 288 engagesthe stud 28I the B key is held thereby in home position and cannot bedepressed. Also rockably mounted on shaft 215 is a lever 282 having ahook 283, formed by its downwardly extending arm, adapted to engage astud 284 on the A key. Said stud 284 is also representeddiagrammatically in Figs. 10, 11, 12, and 13, being located to the leftof stud 28I as shown in Fig. '7. Lever 282 has a cam slot 285 (Fig. 11)accommodating a stud 286 secured to a lever 281 pivotally mounted on astud 288 secured to the left frame plate 8|. When lever 282 is rockedclockwise, hook 283 engages stud 284,. as shown in Fig. 11, preventingthe A key from being depressed, and when rocked counter-clockwise freesstud 284 permitting the A key to be depressed. The forward end of lever281 has a notch 289.

Mounted on a lever 298 (Figs. 10 and 13), which lever is itself rockablymounted on a stud 29I secured to the left frame plate 6|, are two barrellocks, one of said locks 292 (Fig. 10) being associated with the B keyand the other of said locks 293 being associated with the A key. Securednear the rear end of the barrel of lock 292 is a collar 394 (Figs. 10,11, and 14) having a nose 295 on its periphery. Secured near the rearend of the barrel of lock 293 is a collar 291 similar to collar 394having a nose 298 on its periphery. The rear end of the barrel of lock292 terminates in a stud 296 (Fig. 14) and the rear end of the barrel oflock 293 terminates in a stud 299.

A slide 388 bifurcated at its lower end (Fig. 11) to straddle stud 299and having an elongated slot 38I to accommodate stud 29B is permittedvertical motion limited by slot 38I. Slide 388 has a pin 384 secured toit which may be engaged on one side or the other by the nose 295 ofcollar 394 so that when the barrel of lock 292 is turned clockwise, asseen in Fig. 14, slide 388 will be forced to its lowest position andwhen the barrel of lock 292 is turned 360 degrees counter-clockwiseslide 388 will be forced to its highest position. In a similar mannerthe nose 298 of collar 291 cooperates with pin 385 on slide 382 to raiseand lower it. Slide 382 is mounted on stud 299 by means of slot 218which permits and limits its vertical motion, said slide having abifurcated top end 21I to straddle and be guided by stud 298. The factthat the collars 394 and 291 require that the barrels of the locks beturned 360 degrees to function fully causes the keys to be in the samewithdrawing position, either the clockwise or the counter-clockwiseposition. Ears 386 and 381 (Fig. 13) bent over on lever 298 hold theslides 388 and 382 in position on the studs 296 and 299. It Will benoted that the aforementioned movements of slides 388 and 382 arerelative to the locks 292 and 293. Slide 388 has an ear 388 (Fig. 11)which engages notch 211 and slide 382 has an ear 389 which engages notch289, so that relative movement of slide 388 with respect to shaft 215and of slide 382 with respect to stud 288 will move the respectiveassociated levers 219 and 282 either to locking or unlocking positionwith their associated studs 28I or 284 to lock or unlock the respectiveclerks key.

It will be observed that lever 288 (Fig. 10), upon which the locks 292and 293 and the slides 388 and 382 are mounted, is normally heldclockwise on pivotal stud 29I by spring 3 I8 until shoulder 3| I strikesshaft 215. In this clockwise position the levers 219 and 282 will engagethe studs on their associated key when both slides 388 and 382 are intheir up position. Under these circumstances if lever 298 is rockedcounter-clockwise by the operator, the slide 388 will move relatively toshaft 215 and slide 382 willv move relatively' to stud 298 causinglevers 219 and 282 to rock counter-clockwise freeing the A and "B keys.Thus, the rocking of lever 298 counterclockwise until stopped by framemember 83 will supersede the locking action of locks 292 and 293.

Whenever the A" look 293 is locked causing lever 281 (Fig, 11) to berocked clockwise around stud 288, a stud 3 I 2 engages a camming notch313 in a lever 3I4 pivotally mounted on a stud 3I5 carried by the camplate III of the 13" key (see Fig. 10), so that lever 3I4 is rockedslightly counter-clockwise around stud 3I5 positioning shoulder 3I1 overthe key coupler thereby causing every operation of the key coupler tocarry with it the B key cam plate III to operate the B differentialsegment 241. However, if the A lock 293 is locked and the lever 293 ispulled down to supersede the action of lock 293, lever 281 is rockedcounter-clockwise around stationary stud 283 allowing spring 3I6 tounhook shoulder (ill from the key coupler so that both A and B"transactions may be registered.

Control lever A single control lever I10 (Figs. 7, 10 and 13) pivotallymounted on stud 3I3 projecting leftwardly from the left frame 6| has alock 3! on its forwardly projecting arm to lock it in one of fivepositions, diagrammatically shown in Fig. 13, which lever by means ofthe toothed arcuate rear arm cooperates with a pinion 323 (Fig. '1)secured to shaft 238 to turn it differentially. The different positionsof the lever I13 will be referred to as the open drawer, closed drawer,lock register, total, and reset positions.

Secured on the shaft 238 is a cam 32I (Figs. '7, 12 and 13) having a rim322 adapted to block the movement of stud 333, carried by an arm oflever 293, preventing the lever from rocking counter-clockwise fromnormal when the stud is outside the rim, and preventing the lever 293from returning to normal position if the stud is inside the rim. The rimis broken away so that the stud may be moved from outside to inside orvice versa, whenever the shaft is in the reset position as determined bythe control lever. In this manner only the person having a key to thecontrol lever lock may, by shifting the lever to reset position,supersede the control of clerks individual looks 292 and 293.

Another cam 323 (Figs. 7 and 10) is secured on shaft 238 to cooperatewith a stud 324 on a lever 323 rotatably mounted on rod 13. The rearmostend of lever 325 is bifurcated to engage a stud 323 on lever 321rotatably mounted on shaft 90.

A spring 328 anchored to ears on levers 325 and 321 tends to rotatelever 325 counter-clockwise on its axis and lever 321 clockwise on itsaxis, which movement is limited by the engagement of stud $24 with therim of cam 323. Also rotatably mounted on shaft 90 is a lever 329 heldagainst stud 333 by a spring 33I causing lever 329 to move with lever321 positively in a clockwise direction and resiliently in acounter-clockwise direction. The bent over rear end of lever 329 formsan ear having a notch 332 (Fig. '1) cut therein, adapted to cooperatewith a bent over ear 333 (Figs. '1 and 10) on cam I81 secured on themain drive shaft 13. With the machine at rest, the cam I81 is positionedas shown in Fig. 10, and as shaft 18 rotates counter-clockwise the car333 will have to move through notch 332 or by-pass on one side or theother of the bent over car 335 or the machine will not operate due tothe blocking of the main drive shaft. As the control lever, I10positions cam 323 it therefore controls the locking of the machine. Inthe open drawer position of lever I13, cam 323 is positioned so the ear333 passes through notch 332. In the closed drawer position the ear 333will pass over ear 335, if the drawers are closed, and in all otherpositions of lever I13 the ear 333 will be blocked by car 335 thuspreventing a registering operation of the machine. The resilientconnection between levers 321 and 329 prevents strain on the parts ifthe control lever is moved while ear is in the path of movement of ear335.

There is provided, as before mentioned, means for making it necessaryfor both drawers to be closed before the machine is operated if thecontrol lever has been previously set at the closed drawer position.This position of the control lever rocks lever 321 clockwise so ear 333rides over the top of ear 335 if the drawers are closed. It has beenexplained how, when a drawer is open, the latch is held in unlatchedposition by pawl I18 as shown in Fig. 10, until the drawer is closed.This holding up of the latch causes the corresponding one of the twolinks I95 and I96 to be kept in the position to which it was raised bylink I84 on the drawer opening operation. Each of the links 35 and I93has on the front edge of its upper end a notch which is adapted, whensaid links are in normal position and the control lever is in closeddrawer position, to engage stud 333 (Figs. '1 and 10), projecting fromlever 321, so that when either of the links I95 or E33 is raised ondrawer opening operations, the stud 333 will be raised, rocking lever321 slightly counter-clockwise from the position it has assumed uponlever ill] being moved to closed drawer position and instead of the ear333 passing over the top of car 335 it is blocked by the upper half ofear 335 thus locking the machine. As soon as the drawers are closed,lever 321 drops back to the closed drawer position where the ear 333will pass over the top of L. ear 335 when an operation of the machine iscommenced.

On the control shaft 233 being turned to the position it assumes whencontrol lever I13 is in the reset position, the cam 323 rocks lever 321to its most counter-clockwise position which causes stud 333 to forciblycontact the top of the notches in the links I35 and I96 lifting saidlinks and causing both drawers to be unlatched without movement of themain operating means. In this position of the control lever, the lowerhalf of ear 333 blocks ear 333 looking the machine against operation.Thus, when the control lever is moved to position where the totalizersare to be reset the drawers automatically open as they cannot thereafterbe opened by a machine operation, the registering mechanism beinglocked. When the control lever is in look register position the upperhalf of ear 335 blocks ear 333 preventing operation of the register.

The cam 239 (Fig. 8) fastened to shaft 238 and controlling the bellmuffler lock, is turned to unlocking position when the shaft 238 is inreset position thus making the bell mufller mechanism dependent on theoperators power tocontrol lever I13.

Operation In departmentalized cash registers, such as the one hereindisclosed where the departments represent clerks, it is desirable forthe employer to have complete access to all the registering functionswhile each clerk has access only to his own departmental registeringmechanism. In the disclosed machine having two registering departmentsthis desirable result is accomplished by giving the A clerk a key to thelock 293 and the B clerk a key to the lock 292, while the employerretains the key to the control lever.

If the A look 293 is unlocked and the B lock 292 is looked, uponoperation the machine will register in the A totalizer, the A drawerwill open, and the A alarm will sound with or without the use of the Aclerks key, but the B department cannot be selected for registering. Ifthe B lock is also unlocked the A department may be operated as before,but if the B clerks key is used the B department will be selected forthat one operation. If only the B lock is unlocked the B department isalways selected with or without the use of the B key and the Adepartment cannot be selected.

If the control lever is moved to reset position so lever 29%? (Fig. canbe rocked counterclockwise and then the control lever moved to opendrawer or closed drawer position to hold lever 290 in its rockedposition, the machine may be operated whether the locks 292 and 293 arelocked or unlocked, the A department always being selected with orwithout the use of the A clerks key unless the B clerks key is used.

The control lever will also give the employer control over the closeddrawer mechanism and the alarm mechanism, neither of which may be madeoperative or inoperative without having control lever I'm unlocked andmovable.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form orembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.
